' shuttlerail 31 is 10- by which they shuttle rail 31 and parallel shafts 34 and 35 fixed therein. The shafts 34 and 35 at their outer ends support lay sword 12.,

ay casting. 36 having an upwardly extending arm 37. Near each end of the rail 31 the rod 34 passes freelyv through a sleeve 38 forming .'a' portion of a sliding block 39 which is movable vertically in a slot 40 vformed in a casting 41 rigidly secured to the The vertically movable rods ends fast in the blocks 39' and at their lower connected to. -levers.43. A plate 28 (previouslyrdejsoribed) is secured to each rod 42 (the left hand plate 'and rod being shown in are fixed at' one en d' upon a sha-ft 44, .angularly movable in bearingssupported upon the loom side. A rearwardly and upwardly extending lever- 45 (Figs. land 4) is also secured to the shaft 44 and'is provided at its upper end with a roll 46 positioned to engage a cam 47 mounted u on the continuously rotating cam shaft he lever 45 has a lug 48 Aupon one side thereof positioned to engage a latch 49 mounted upon a fixed pivot 50. The latch 49 is connected by acord 51 with a Jacquard or other pattern-controlledl mechanism (not The normal position of the lever 45 is that shownin-'Fig4 in which position. itis retained by the latch 49. The forward ends 'of the levers 43 are then in raised position and the rods 42, the fplate 28 and theyshuttle rail 3l are also raised therewith. The

shuttle rail is then in inoperative position,

I when, the -latch 49 and the lug strap connections engages the lugs upon the pick lever arms and thereby 'operate the fly'shuttle.

The patternmechanism islso timed that,I 'is lifted' to release the lever, the roll 46 will be in engagement `.vith one of the points of the cam 47 (as shown in ybroken lines in Fig. 4). Aslong as thev latch is held up' by the pattern mechanism, the roll 46 will followthe cam 47, thereby raising. and lowering the shuttle rail at each reciprocation of the lay. This operation continues -until the latch is released by the pattern mechanism to again engage the lug v 48 on the lever 45.

I willnow describe the mechanism for selectively reciprocating the Iswivel shuttles. Referring to Fig. 2, aplurality -of bell cranks 50are mounted upon a stud 51 sup# ported by the upwardly extending arm 37- ofthe casting 36.4 The depending-arm of end they are pivotally will be raised and a; vroll 75 engaging a each bell 'crank is connected by a rod 52 to-a sliding rack or other suitable mechanism for reciprocating the swivel shuttles 30, aseparate bell crank land connecting rod being provided for each bank of shuttles. The horizontally extending arm of each bell crank is pivotally -connected to a cap 53 mounted upon the 1e cap and rod are-screwconnected, thus providing for relative adf justment and they are retained in adjusted position by -check nuts 54a.

1n a cam groove 60 formed in the radial surf ace of a disk 61 loosely mounted u pon the shaft 44. The disk 61 is provided with a series of recesses or notches '62 in its edge,

-these notches being engagedby a roll 63 on a locking lever64 carried by the lever 45. A spring 65 is connected at one end to the locking lever 64 and lever 45. and forces the roll 63 yieldingly into one of the notches 62. Inasmuch as the levers 43 and 45 and also the a-rm 57 are all rigidly secured to the shaft 44 and as the cam disk 61 is yieldingly locked to the lever 45, it will be seen that the parts thus far described for reciprocating the swivel shuttles lowered simultaneously with the shuttle rail without causing relative movement between the parts of the shuttlereciprocating mechanism. The shape of the cam groove 60 is clearly show-n in Fig. 4 and .it is evident that rotation of one of the disks 61 upon the shaft 44 `must result in alternately raising and lowering one of the rods 54, thereby reciprocating one bank of swivel shuttles.

I will now describe the devices for rotating the disks 61 and for selectively determiningthe time of such rotation. On the side of the disk 61 opposite to the groove 60 3) engaged by upper end of a vertically movable rod 54. Tl

at the other -end to the At their lower ends, the rods 54 are connected to levers 55 arm of a two-armed carrier 68 and forced i yieldingly. into such engagement by a spring 69. The other arm of -the carrier 68 is pivotally connected to the lower end of a swinging plate 70 (Fig. v3) slot 71 therein. A lever 72 is mounted upon lixed pivot 73 and is provided with a transversely .extended head 72 l (Fig. 5)

through which a stud 74 extends and enters the slots l71 of the-separated swinging plates 70. At itsopposite end the lever 72 carries constantly rotatin cam76 mounted upon Athe cam shaft 23.

having an L-shaped Aintensas -slot and boltlconnectionis provided between tlie"ca1n`f76 and the cam 47, whereby they mav be angularly securedto each other.

Each platev 70 is yieldingly drawn toward the left by a-sprngy77 secured to a 'fixed portion-ofthe loom and is movablein thelv opposite .direction by a cord 78 controlled I by 'arJacquard or other'pattern mechanism WVhen theplate 70 is in the normal position shown in Fig; 9, the constantly reciprocating stud 74 is freely movable vertically 'i along the longitudinal branch of the slot 71.

Whenthe reciprocation of a particular bank of swivel shuttles. is desired the plate 70 which controls that bank of shuttles is moved bythe pattern mechanism from the position shown in'Fig. 9 to that shown -in Fig. 1, the

studi-1w74:vr being thereby positioned ini the transverse portion of .the'slot 71.v j p .-..`;At its next` vertical movement the stud 71 will carry the plate 70 with it thereby moving the pawlcarrier 68 (Fig. 3) and the pawl 67 to 'rotate the disk G1 a single'step forward.L This angular movement of the disk G1 will result' in moving the swivel shuttles 4in thevselected bank from one'end to the other of their path of travel.

To-,prevent possible disconnection of the I stud 74.*a'nd the' plate 70 during the vertical movement ofthe plate, I provide a fixed stud .79 `which engages one side of the plate 70 as the upward movement of the plate begins (Fig. 3) and thereafter prevents lateral movement of the plate relatively to the stud 74. At its eXtreme upper end the edge of the plate 70 is provided with a cut away [portion which permits lateral movement of the platewhenin its normal lowered position. l f v i y l A screw. 81 is mounted in each `plate 7 0 near, itslower end 'and constitutes an adjustable stop for determining the normal vertical 1position of the plate, the screw 81 coperatingjfor this purpose with'a lug 82 upon the carrier 68 (Figs. -1 yand 3).l A

an extension 91 of the vcasting 4 1 depending armf921ofthebellgcrmkxw carries arear projection 93p sitiontelclbetweenvertical surfaces formed uponjcasting `911 secured tothe' 'rod 341, the partsil?) and 94 forming a-sliding connection between thel'bell crank andthe shuttle grail.v The laterally p-roject/I'igffikm, Of 90 'is' ota'lly connected.A to a 'cap threadedjupon ing surfaces 102 and 103.

At its lower-end the rod 97 is pivotallyconnected to a lever 99 (Fig. 6)-inounted'upon a fixed pivot 100 and having annpwardly' projecting arm 101 movable therewith. The

arm 101is provided with downwardly convergingsurfaces 102-103 positionedfor engagement by pins v10-1mounted ina rota- .table disk 105. A plurality of `pins 101are provided. andeach pin is `adjustable in substantiall-y radial slots in the disk 105. The

pins 101 may be provided with rolls if so desired. f Upon its side opposite to the pins 104: the disk 105 is provided with a plurality of rearwardlyprojecting pins 10G (Fig. 7) corresponding in number to the pins 104 and positionedfor engagement by -a pawl 107. The pawl 107 is pivotally connected to a lever 108'mounted upon a fixed pivot 109 and' carrying al roll 110 positioned to engage the cam 17previously described. As the roll 110 is forced outward by the cam vthe p'awl 107 will be actuated to feed thedisk v105 one step` in the direction of the arrow shown in Fig. r0, thereby.positioning the next successive pin 101 between the convergf rThe normal position of the disk is shown in Fig. 1 in which a pin 104 is positioned between the inner end portions of surfaces 102 and 103, l thus locking the arm 101 from movement in l either direction. y

The disk 105 is yieldingly held in its normal position by a spring pressed roll 111 (Fig. 0) mountedl upon an arm 112 yieldingly forced against the disk by a coil spring 113.: .The lever 108 has aprojection :114 formed yon one side. thereof, said projection being connected by a cord 1`15with aA Jac-jy lqual-dor other patternmechamsm. A coll spring 116 is inserted between the pawl 107 and the projection 114- the spring forcing the pawl yieldingly upward-to 'engage the pins 106. After the roll 110 has been forced to the right (as-viewed in Fig. 6) by the caifi 17 it' will remain in its outward-position until moved inward 'by the pattern mecha-l nism. The inward movement of the roll 110 is accompanied by an outward movement lofI the pawl 107'to engage the pin 106 next in order. The `pins104 may beplaced in any desired order and at any desiredvdistances .fromfthe center thereby permitting a considerable number of different transverse positions of theigures with reference to the warp;
